Abstract: A method for providing a platform-independent unified simulation model representing a road vehicle includes a vehicle dynamic model configured to simulate a time evolution of at least one motion state of the vehicle, a plurality of actuator sub-models, each of which represents an actuator in the vehicle, configured to simulate a time evolution of a motion state under the action of the actuator controller sub-models representing electronic control unit, ECUs, which are configured to control the actuators on the basis of a sensed state of the vehicle and in accordance with predefined control logic, and to exchange bus messages with other ECUs, and a communication sub-model representing a data bus operable to deliver bus messages among ECUs.

Abstract: A computer-implemented method of deriving a vehicle dynamic library including at least two optimized vehicle dynamic implementation models is provided. The method comprises defining at least two operational design domains, choosing one vehicle dynamic abstract model, choosing one vehicle dynamic implementation model to be optimized, simulating the vehicle dynamic abstract model for each operational design domain, wherein the simulation generates reference trajectories, optimizing the vehicle dynamic implementation model for each operational design domain so as to create at least two optimized vehicle dynamic implementation models, wherein each optimization is based on at least one of said generated reference trajectories, validating each optimized vehicle dynamic implementation model to achieve a validation level for each optimized vehicle dynamic implementation model, and saving each optimized vehicle dynamic model together with its validation level.
